I'm getting the following when trying to create a trove DB in codfw1dev in horizon:
Failed to create volume for instance 722cdd73-3715-4fdc-b750-fdca3a3e980e VolumeLimitExceeded: Maximum number of volumes allowed (4) exceeded for quota 'volumes'. (HTTP 413) (Request-ID: req-6c525851-1e96-4c2d-8253-0254d7374bdb)
Volumes quota is currently at 15, using 6
The DB volumes quota was 10 I raised it to 20, though in any case it is using 3
# openstack database quota show paws-dev +-----------+--------+----------+-------+ | Resource | In Use | Reserved | Limit | +-----------+--------+----------+-------+ | backups | 0 | 0 | 2 | | instances | 3 | 0 | 10 | | ram | 3072 | 0 | -1 | | volumes | 3 | 0 | 20 | +-----------+--------+----------+-------+
Some searching suggests it could be the cinder volumes, though that seems linked to the project volume allocation, as it changes when I change the volume quota:
# cinder quota-usage paws-dev +----------------------------+--------+----------+-------+-----------+ | Type | In_use | Reserved | Limit | Allocated | +----------------------------+--------+----------+-------+-----------+ ... | volumes | 6 | 0 | 15 | |
Snapshots was showing 4 for a quota, so I updated it, though the error still shows a maximum of 4. I'm not sure where openstack got this value.
